Observation Sector 12

TESS Observation Sector 12 is comprised of observations made during orbits 31 and 32 of the TESS mission.  Observations of Sector 12 extend from the 21st of May to the 18th of June. The regions of the sky observed during Sector 12 are shown at right. The targets observed during Sector 12 are below.

Pointing

During Sector 12, the instrument axis is pointed to 253° ecliptic longitude and -54° ecliptic latitude.
The orientation of the camera array in celestial coordinates is:
RA (J2000): 229.5885°
Dec (J2000): -75.1256°
Roll (deg): 153.9773°
The coordinates of the centers of the fields-of-view of the four cameras are given in the table below.

Map of TESS camera fields-of-view for Sector 12 in ecliptic coordinates.  Camera 1 is red, camera 2 is magenta, camera 3 is blue, camera 4 is green.  The field of camera 4 looks distorted because it is centered on the ecliptic pole. The thin black line is the ecliptic; the thick black line is the galactic plane.

Targets for Sector 12

During Sector 12, 20,000 stars are observed at two-minute cadence, and full-frame images are collected every 30 minutes.
The list of targets observed at two-minute cadence are given on the Target List page. The target list includes the camera and CCD on which the target can be found, TIC ID, RA, declination, and TESS magnitude.
